jcheckbox issues need help. thanks.
hello, i am making a hall pass program for my computer programming class. i am having issues with my jcheckboxes. first off. this file reads from a .txt that just has
greg
john
joe
54343
45777
33444
in it. after the user puts in a correct id number, it displays 4 checkboxes to where they want to go. bathroom, office, nurse, and other. once the user clicks one of the checkboxes, it will remove all the stuff from the panel, and add the name of the person and the time they left. the problem i am having is when the user clicks the checkbox , nothing happens. run this for yourself and see for yourself what happens (if you want of course) this is my final assignment for computer programming and i need help bad lol. i have added an itemlistener, that when the checkbox is selected a boolean = true, then in the actionevents, when the "submit" button is pressed, and the id is correct, and the checkbox boolean is true, it removes all the stuff and puts in all the new elements. i want to say that only the bathroom checkbox has the stuff that it should have to make it work , like added the name and time to the second screen after the 4 checkboxes. also i would like to add that this program compiles just fine, just nothing happens when i click the checkboxes. THANKS IN ADVANCED

i make my own version of it, can't really stand ur indentation lol, if u still insist on ur version just take the related chunk and implement it urself
i don't quite understand what u want but the way i done is
>enter id
>check id from names.txt
>if exist ask to select where to go (bathroom, office, nurse, others)
>open next page showing the name of the ID, going to where and when

The show method was deprecated in j2se 1.5. Look up the method in the Window api to see that it has been replaced by setVisible. If you are using an older version then setVisible will work okay (since 1.1);
just nothing happens when i click the checkboxes
Actually, they are radio buttons.
The code logic in the ItemListener was faulty and the code to reset the gui components was buried/hidden/not_accessible in the actionPerformed "submit" block.
Many changes and some suggestions.
When you change/alter the components in a container you must tell the container to renew its layout. We do this with either the Container method validate or the JComponent method revalidate.

thanks
hello . hey thanks for the help on this. when it shows the "red screen" i want to display the users name that logged in , instead of just "array[0]" so after you choose the checkbox it displays the right name.
